Formby Labour Action Team has contacted Sefton Council to call for emergency leaf and litter clearing from many of the town's gutters.
On an inspection of drains in the town, Formby Labour Action Team leader Peter Maguire and MP Bill Esterson found that many kerb-side grids are totally blocked with leaves and litter.
The issue was raised by residents in various locations throughout Formby, with a large number of complaints from householders in Raven Meols Lane.
Peter, who is also Labour's candidate for Ravenmeols Ward at next May's local elections, said he was concerned about flooding because of drain blockages.
Peter said: "Formby Labour Action Team has received a number of complaints from residents complaining that the gutters and grids have become so blocked with litter and leaves that large puddles are forming even during fairly light rainfall.
"But when we have rainfall like we had just last week, then those puddles can become treacherous for vehicles and even pedestrians.
"Living near to Raven Meols Lane myself, I know that that is one road which is particularly bad. Driving along there after a rainfall really can be quite dangerous."
Peter is urging people to contact him with reports of problem grids so the Labour Action Team can then request action by Sefton Council.
Peter said: "Our MP Bill Esterson and myself took a look at some of the grids at various locations in Formby and many appear to be totally blocked by leaves.
"There's nothing we can do about falling leaves, but we should be allowing them to block drains.
"We have already contacted Sefton Council asking for action at some of the worst affected grids, but if people know of other grids which have become blocked, please get in touch and we'll add them to the list."
